Which phrase describes a feature of igneous rocks that cool quickly during formation?
small crystals
coarse surfaces
O found beneath Earth's surface
O exposed after erosion occurs

Answers

Answer 1

Answer: I would go with "esposed afer erosion occurs".

Explanation:

Erosion can cause things to be rough, ridgid, and coarse, but it can also smooth things out. I would choose B in this situation. :-)

Answer 2

Small crystals is a feature of igneous rocks that cool quickly during formation.

Hence, the correct answer is option a.

Igneous rocks that cool quickly during formation exhibit certain distinctive features:

1. Fine-Grained Texture: Rapid cooling prevents the growth of large mineral crystals, resulting in a fine-grained texture. The individual mineral grains are too small to be visible to the na'ked eye.

2. Glassy Texture: In some cases, extremely rapid cooling can lead to the formation of a glassy texture, where the rock appears similar to glass and lacks any crystalline structure.

3. Lack of Visible Vesicles: Vesicles, which are gas bubbles trapped in the rock during cooling, tend to be smaller or absent in quickly cooled igneous rocks. The lack of vesicles suggests limited gas escape due to the rapid solidification process.

4. Lack of Pegmatitic Textures: Pegmatitic textures, characterized by exceptionally large crystals, are not typically found in quickly cooled igneous rocks since these crystals require a slower cooling process to form.
